TAPE FEED AND MOESTENING MACHINE.

Tlo all 'whom 'it may concern.'

Be it yknown that l, RUFUs MARION BROOKS, a citizen of the United States, and a resident of Roseburg, county ofDouglas, and State of Oregon, have invented a new and useful Tape Feed and Moistening Machine, of which the following is a specification.

The present invention relates to improvements in tape feeding and mostening devices such as are frequently used in stores for the convenient handling of adhesive tape. A special ob'ject'of my invention is to provide means by which a portion may be separated from a roll of adhesive tape by merely pressing on a footvpedal and in which the separated piece is moistened simultaneously so that it is ready for immediate use.

With this object in view I illustrate the preferred form of my invention in the accompanying drawin s, in which 4Figure 1 is a side elevation cfg my device; Figure 2 a top plan view of the same; Figure 3 an enlarged section taken along line lll-Ul of Figure 2; Figure 4 a detail view showing the cutting means inmy device; Fi re 5 a longitudinal sectionthrough my evice, a portion being left away; Figure 6 a sectional view along line Vl-Vll of Fi re 2; Figure 7 a cross section taken along ine VII- VH ofFigure 1; Figure 8 a perspective detail view of a liquid receptacle used in my device; Figure 9 a detail view graphically illustrating the principal working movement of my device, and Figure 10 a detail view of a felt member used in my device. While the drawings show the preferred embodiment of my invention, l wish to point out that the same may be modified in many details without departing from the spirit of the present invention.

My device is mounted on the plate (l) havingl a. ange (2) and being secured by means of screws or in any other well known manner to the top of a counter or desk or table, wherever it is to be used, in such a manner that the left hand portion of the device as disclosed in Figure 1 extends beyond the edge. of the sup ort. From the rear portion of the late 1)rse two parallel supportin mem ers (3) supporting the `horizontal sha (4) on which the spool (6) of adhesive tape is mounted in such a manner that the adhesive side of the tape is turned outward. The members (3) are preferably mounted in such a manner that they slightly converge toward each other so as to exert a light pressure on the spool of tape and thereby cause the latter to offer slight resistance to the unwinding of the same. Forwardly of the spool of tape a vertical supporting member (7) is secured to the flange (2) and carries the two horizontal pins (8) and (9'). The former pin pivotally supports a guide way (11) for the tape, which is shown in cross section in Figure 7, from which it will be seen that it has an arched cover (12) and a channel (14). This guide leads to the cutting device illustrated in Figure 4 which comprises a blade (16) bent into angular shape and provided with a perforation (17) at or near its heel adapted to it Onthe (18) rising from the plate (1), and a clamp (19) also secured in the plate (1) adapted to be pushed over one end of the blade so as to hold the other end (21) which represents the cutting edge of the blade firmly against the end of the guide way. It will be seen that the tape when forced through the guide way will assume its arched shape and that if the end of the guide way which is in contact with the blade is pressed downward the cutting edge (21) will engage the tape, beginning at the two edges and working towards the center so as to cut the same with scissors like action.

To impart motion to the tape l use the Wheel (22) mounted onthe pin (9) which is adapted at certain times to bear against the under side of the tape and when rotated to advance the tape in the uide way. The wheel is preferably surroun ed with a rim (23) made of rubber. It is actuated by vmeans of the drum (24) loosely mounted on the saine pin (9) and provided with a belt (26) one end of which is secured to its rim while the other end, after passing around the drum, is led downwardly through the top of the counter to be joined as shown at (27) with a rod (28) adapted to be actuated by a foot pedal not shown in the drawing. The drum is provided on its inside with suitable spring means counter-acting a, pull on the belt (26) so that immediately after the latter belt has been released the spring returns the drum to its original position. As shown in Figure 3, there is pivotally secured on the drum the awl (31) engaging la toothed wheel (32) willich is rigid on the shaft. The pawl actuates the toothed wheel in one direction only so that the drum rotates the wheel (22) when actuated by the belt (26), but does not rotate the wheel when turned in the other direction b its spring. y-The drum is also provided with a cam (33) the shape of which is shown in Figure 1. The cam is designed to co-operate with a stud (34) extending sideways from a metal member (36) forming an integral rear portion of the guide way (11).

The cam is adapted to engage the stud withits front face as well as with its rear face,

yand in either case it raises the stud (34) and thereby pivots the guide wa (11) on its support (8). The front face (337) of the camcauses a more pronounced pivotal motion of the guide way (11 however, than the rear face (38). The t ree possible positions of the guide way are illust-rated in Figure 9 and the operation of the cam may be explained as follows:

When the belt (26) is pulled downward by means of the foot pedal t-he drum rotates counter-clockwise, the stud (34) becomes disengaged from the rear face (38) of the cam and falls down on the surface of the drum so that the rear end of the guide way assumes its lowest position, as indicated in the dash and dot lines in Figure 9. To cause the stud to engage the surface of the drum immediately after being released from the rear face of the cam I provide a spring (39) on the shaft (8) as shown in Figure 6 which lhas a tendency to press the front end of the guide way upward and its rear end downward. In this position the guide way remains until the drum has nearly completed a -full turn, at which time the stud (34) becomes engaged by the front falce (37) of the cam which raises the rear end of the guide way and forces down its front end into the position shown in dotted lines in Figure 9. During this movement of the guide way the tape which extended through the ide way is cut by the cutting edge (21) of t eblade (16). In the meantime the operator has released the foot pedal and under the influence of its spring the drum returns in a clockwise rotation to its original position. While thus travelin the stud (34) remaining in contact with t e surface of the rim of the drum returns the guide way (11) to the dash and dot line position of Figure 9 and is forced at the end of its rotation into contact with the rear face of the cam (33) whereby it is again slightly elevated into the position shown in full lines in Figure 9. In this position the guide is lifted sufficiently to disengage the tape from the wheel so that when the device is inactive the tape clears the rim of the wheel. I deem this a valuable feature the rod (28) under the continuous pressureof the wheel against the tape and the guide way the former might stick to the guide way and thereby render the apparatus inoperative.

The guide way leads the tape to the moistening device which comprises a receptacle (41) preferably filled with water and provided with a small arch (42) which spans the two perforations (43) through which a strip of felt may be inserted into the receptacle so that its ends extend into the water and its central portion rests on the arch "(42). The tape slides underneath the arch (42) and after passing the same comes in contact with the felt (44) in the manner illustrated in Figure 5, the felt beingkept moist by capillary attraction.

The fact that the guide way has an arched top and thereby imparts the same shape to the passing tape presents two advantages: in the first place, it facilitates the proper cutting of the tape, and in the second place it stiffens or braces the tape so that the latter will ina-ke aV better contact with the moistened felt. A cap (46) covers the felt and is secured on the receptacle by means of two clips (47) adapted to be pressed into the perforations (43) alongside the felt (44).

Aspecial means for securing the belt (26) to the rod (28) is shown in Figure 1 and comprises a sleeve (48) adapted to receive the end of the belt as well as the end of the rod (28), the latter being provided with a hook (49) adapted to be received in a recess (51) of the sleeve (48). A setscrew (52) penetratesthe sleeve (48) and. presses into firm contactl with the lower end of the belt (26) so that neither the belt nor the rod can be withdrawn from the sleeve as long as the screw (52) is tight.
